When a plunger of a high pressure pump is rising, a high pressure pump controller closes a regulator valve by energizing a solenoid of an electromagnetic actuator of the high pressure pump to discharge fuel into a delivery pipe. Further, this fuel discharge energization is stopped before the plunger reaches top dead center at a pump TDC timing. Further, a fuel pressure of the delivery pipe is detected at the pump TDC timing, and based on that detected value, a time Td from the pump TDC timing until a valve opening timing of the regulator valve is estimated. Once the estimated time Td elapses from the pump TDC timing, the solenoid is reenergized to removed a movement speed of a movable portion in a direction that pushes the regulator valve in an opening direction.

The present invention can speedily and accurately estimate an SOC of a secondary battery immediately after a charge/discharge operation resumes. A determination unit determines whether a dormant period is longer than a predetermined time in response to an initiation of power supply from a secondary battery to a motor generator. The dormant period is equivalent to the duration from a previous stop of power supply to a present initiation of power supply. If the dormant period is longer than the predetermined time, a state-of-charge estimating unit sets an initial SOC based on a peak battery voltage drop &#x394;Vs and a peak discharge current Is, wherein the peak battery voltage drop &#x394;Vs represents a difference between a battery voltage Vo measured before initiating power supply and a lowest battery voltage Vs measured after initiating power supply and the peak discharge current Is represents a maximum current value measured after initiating power supply. The state-of-charge estimating unit estimates a state of charge of the secondary batterybased on the initial SOC as a value effective immediately after initiating power supply.

A cooling apparatus includes a refrigerant tank having a surface to which heating devices are attached and containing liquid refrigerant which is boiled and evaporated by heat transferred from the heating devices, and a radiator for radiating the heat of the boiled and vaporized refrigerant. The radiator has an inflow return chamber provided with a small-diameter opening having a diameter smaller than that of the inflow return chamber. The liquid refrigerant of the gas-liquid mixed refrigerant is dammed by the small-diameter opening of the inflow return chamber and the dammed liquid refrigerant is returned through a return passage to the refrigerant tank. Since the liquid refrigerant contained in the gas-liquid mixed refrigerant is suppressed from flowing by means of the small-diameter opening, the gaseous refrigerant can transfer heat directly to the walls of the radiating passages, so that the deterioration of the radiating performance can be prevented.

Cooling apparatus boiling and condensing refrigerant

According to the present invention, a cooling apparatus using boiling and condensing refrigerant, includes a fluid separating plate for separating a high-temperature fluid from a low-temperature fluid, a refrigerant tank disposed on the side of the high-temperature fluid from the fluid separating plate, a refrigerant sealed into the refrigerant tank, a pair of communication pipes, one end of which is communicated with the refrigerant tank hermetically, a condensing portion communicated with the other end of the communication pipes and disposed on the side of the low-temperature fluid from the fluid separating plate, and a heat insulating material as a high-temperature portion-side heat insulating material coated on the outer periphery of the high-temperature-side communication pipe. In this way, it is possible to suppress a heat conduction from a high-temperature portion (high-temperature air) to the high-temperature-side communication pipe. As a result, it is possible to prevent the descending refrigerant which has been condensed and liquefied in the radiator from receiving heat from the high-temperature portion through the high-temperature-side communication pipe to receive an ascending force in the high-temperature-side communication pipe.
